You have some of the best learning videos I've seen on you tube and I'm enjoying learning while watching them. I fall into the sad programer category where nothing will work and I try to plan accordingly. The drum sequencer is a great idea but you have no comunication error check. If you lose comunication the drum will "stall" and comunication will never be re-established.
